Example of settings to CMake I use

Overrides RelWithDebugInfo from '-O2' to '-Og'
Also sets TYPE to 'Debug'
And example of setting the Eclipse executable path.

alias ncmake='CXX=g++ CC=gcc cmake -DCMAKE_C_FLAGS_RELWITHDEBINFO="-Og -g -DNDEBUG" -DCMAKE_CXX_FLAGS_RELWITHDEBINFO="-Og -g -DNDEBUG" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_ECLIPSE_MAKE_ARGUMENTS=-v -DCMAKE_ECLIPSE_EXECUTABLE=/home/bo/eclipse/cpp-mars/eclipse/eclipse  -DCMAKE_ECLIPSE_VERSION:STRING="4.5 (Mars)" -G "Eclipse CDT4 - Ninja"'
